+The Adafruit breakout board HT16K33 is supported on I2C address 0x71 and 0x72.
+Address 0x72 is only used if 0x71 is also available.\\
+Starting with version 1161 the "All Call" 0x70 address is no longer used to avoid conflicts on the I2C bus.\\
 It displays alternate time, date and temperature.\\
 With the ''NTP_CLOCK'' USERCNF.h setting the "pool.ntp.org" service will be used to get the time of day instead from the Rocrail server. It will not alternate between date and temperature.\\
